请看这个题目，选哪个最佳?
_________ was very _________ that little Jim wrote the letter.
A. It, careful B. It, carefully C. He, careful D. He, carefully
【分析】此题正确答案为B，其余几项均有可能被误选。误选的原因主要是将第二空所填之词视为动词 was 的表语，从而误选了形容词 careful，并以此为依据在第一空误填了代词 He，误认为 He was very careful 是一个句子意群。其实，此题是一个强调句，其非强调形式为 Little Jim wrote the letter very carefully. 若用 it is that 的强调句式强调其中的状语 very carefully 即为上面一题的题干。请看下面几例，也属强调结构：
(1) It was when she was about to go to bed _________ the telephone rang.
A. since B. as C. that D. then
答案选C，被强调成分为 when she was about to go to bed 这一时间状语从句。
(2) It may have been at Christmas _________ John gave Mary a handbag.
A. before B. who C. that D. when
答案选C，被强调成分为 at Christmas，其中的动词 be 采用了 may have been 这一较为复杂的形式。
(3) Who was it _________ saved the drowning girl?
A. since B. as C. that D. he
答案选C，被强调成分为 who，该句实为 It was Tom that saved the drowning girl. 这一强调句的特殊疑问句形式(即对其中的Tom 提问而得)。
(4) What is it _________ his daughter needs most?
A. what B. which C. that D. if
答案选C，被强调成分为 what，该句实为 It is a bike that his daughter needs most. 这一强调句的特殊疑问句形式(即对其中的bike 提问而得)。
(5) It was not until he came back _________ he knew the police were looking for him.
A. which B. since C. that D. before
答案选C，为 He didnt know the police were looking for him until he came back. 之强调句式。注：notuntil的强调句式通常为 It was not untilthat 的形式。
